PRINCIPLE OF PUMP OPERATION
This flap swing check valve pump is powered by compressed air and is a 1:1 pressure
ratio design. It alternately pressurizes the inner side of one diaphragm chamber, while
simultaneously exhausting the other inner chamber. This causes the diaphragms, which
are connected by a common rod, to move endwise. Air pressure is applied over the
entire surface of the diaphragm, while liquid is discharged from the opposite side. The
diaphragm operates under a balanced condition during the discharge stroke, which
allows the unit to be operated at discharge heads over 200 feet (61 meters) of water
head.
Since the diaphragms are connected by a common rod, secured by plates to the
center of the diaphragms, one diaphragm performs the discharge stroke, while the other
is pulled to perform the suction stroke in the opposite chamber.
For maximum diaphragm life, keep the pump as close to the liquid being pumped as
possible. Positive suction head in excess of 10 feet of liquid (3.048 meters) may require
a back pressure regulating device. This will maximize diaphragm life.
Alternate pressuring and exhausting of the diaphragm chamber is performed by
means of an externally mounted, pilot operated, four-way spool type air distribution
valve. When the spool shifts to one end of the valve body, inlet air pressure is applied to
one diaphragm chamber and the other diaphragm chamber exhausts. When the spool
shifts to the opposite end of the valve body, the porting of chambers is reversed. The air
distribution valve spool is moved by an internal pilot valve which alternately pressurizes
one side of the air distribution valve spool, while exhausting the other side. The pilot
valve is shifted at each end of the diaphragm stroke by the diaphragm plate coming in
contact with the end of the pilot valve spool. This pushes it into position for shifting of
the air distribution valve.
The chambers are manifolded together with a suction and discharge check valve for
each chamber, maintaining flow in one direction through the pump.
INSTALLATION & START-UP
Locate the pump as close to the product being pumped as possible, keeping suction
line length and number of fittings to a minimum. Do not reduce line size.
For installations of rigid piping, short flexible sections of hose should be installed
between pump and piping. This reduces vibration and strain to the piping system. A
pulsation dampener is recommended to further reduce pulsation in flow.
This pump was tested at the factory prior to shipment and is ready for operation. It is
completely self-priming from a dry start for suction lifts of 20 feet (6.096 meters) or less.
For suction lifts exceeding 20 feet of liquid, fill the chambers with liquid prior to priming.
AIR SUPPLY
Air supply pressures cannot exceed 125 psi (8.61 bar). Connect the pump air inlet
to an air supply of sufficient capacity and pressure required for desired performance.
When the air line is solid piping, use a short length of flexible hose (not less than 3/4"
(19mm) in diameter) between pump and piping to eliminate strain to pipes.
AIR INLET & PRIMING
For start-up, open an air valve approximately 1/2" to 3/4" turn. After the unit primes,
an air valve can be opened to increase flow as desired. If opening the valve increases
cycling rate, but does not increase flow rate, cavitation has occurred, and the valve
should be closed slightly.
For the most efficient use of compressed air and the longest diaphragm life, throttle
the air inlet to the lowest cycling rate that does not reduce flow.

AIR VALVE LUBRICATION
The pump’s pilot valve and main air valve assemblies are designed to operate
WITHOUT lubrication. This is the preferred mode of operation. There may be
instances of personal preference, or poor quality air supplies when lubrication of the
compressed air supply is required. The pump air system will operate with properly
lubricated compressed air supplies. Proper lubrication of the compressed air supply
would entail the use of an air line lubricator set to deliver one drop of 10 weight, nondetergent
oil for every 20 SCFM of air the pump consumed at its point of operation.
Consult the pump’s published Performance Curve to determine this.
It is important to remember to inspect the sleeve and spool set routinely. It should
move back and forth freely. This is most important when the air supply is lubricated.
If a lubricator is used, oil accumulation will, over time, collect any debris from the
compressed air. This can prevent the pump from operating properly.
Water in the compressed air supply can create problems such as icing or freezing
of the exhaust air causing the pump to cycle erratically, or stop operating. This can be
addressed by using a point of use air dryer (available from Warren Rupp) to supplement a
plant’s air drying equipment. This device will remove excess water from the compressed
air supply and alleviate the icing or freezing problem.
EXTERNALLY SERVICEABLE AIR DISTRIBUTION SYSTEM
Please refer to the exploded view drawing and parts list in the Service Manual
supplied with your pump. If you need replacement or additional copies, contact your
local Distributor, or the factory Literature Department at the number shown below. To
receive the correct manual, you must specify the MODEL information found on the
name plate of the pump.
MODELS WITH 1" SUCTION/DISCHARGE OR LARGER AND
METAL CENTER SECTIONS
The main air valve sleeve and spool set is located in the valve body mounted on the
pump with four hex head capscrews. The valve body assembly is removed from the
pump by removing these four hex head capscrews.
With the valve body assembly off the pump, access to the sleeve and spool set is
made by removing four hex head capscrews (each end) on the end caps of the valve
body assembly. With the end caps removed, slide the spool back and forth in the sleeve.
The spool is closely sized to the sleeve and must move freely to allow for proper pump
operation. An accumulation of oil, dirt or other contaminants from the pump’s air supply,
or from a failed diaphragm, may prevent the spool from moving freely. This can cause
the spool to stick in a position that prevents the pump from operating. If this is the case,
the sleeve and spool set should be removed from the valve body for cleaning and further
inspection.
Remove the spool from the sleeve. Using an arbor press or bench vise (with an
improvised mandrel), press the sleeve from the valve body. Take care not to damage
the sleeve. At this point, inspect the o-rings on the sleeve for nicks, tears or abrasions.
Damage of this sort could happen during assembly or servicing. A sheared or cut o-ring
can allow the pump’s compressed air supply to leak or bypass within the air valve
assembly, causing the pump to leak compressed air from the pump air exhaust or not
cycle properly. This is most noticeable at pump dead head or high discharge pressure
conditions. Replace any of these o-rings as required or set up a routine, preventive
maintenance schedule to do so on a regular basis. This practice should include cleaning
the spool and sleeve components with a safety solvent or equivalent, inspecting for signs
of wear or damage, and replacing worn components.
To re-install the sleeve and spool set, lightly lubricate the o-rings on the sleeve with
an o-ring assembly lubricant or lightweight oil (such as 10 wt. air line lubricant). Press
the set into the valve body easily, without shearing the o-rings. Re-install one end cap,
gasket and bumper on the valve body. Using the arbor press or bench vise that was used
in disassembly, press the sleeve back into the valve body. You may have to clean the
surfaces of the valve body where the end caps mount. Material may remain from the old
gasket. Old material not cleaned from this area may cause air leakage after reassembly.
Take care that the bumper stays in place allowing the sleeve to press in all the way.
Reinstall the spool, the opposite end cap, gasket and bumper on the valve body. After
inspecting and cleaning the gasket surfaces on the valve body and intermediate, reinstall
the valve body on the pump using new gaskets. Tighten the four hex head capscrews
evenly and in an alternating cross pattern.

that the bumper stays in place allowing the sleeve to press in all the way. Reinstall the
spool, opposite end cap, gasket and bumper on the valve body. After inspecting and
cleaning the gasket surfaces on the valve body and intermediate, reinstall the valve
body on the pump using new gaskets. Tighten the four hex head capscrews evenly and
in an alternating cross pattern.
AIR EXHAUST
If a diaphragm fails, the pumped liquid or fumes can enter the air end of the pump,
and be exhausted into the atmosphere. When pumping hazardous or toxic materials,
pipe the exhaust to an appropriate area for safe disposition.
This pump can be submerged if materials of construction are compatible with the
liquid. The air exhaust must be piped above the liquid level. Piping used for the air
exhaust must not be smaller than 1" (2.54 cm). Reducing the pipe size will restrict air
flow and reduce pump performance .When the product source is at a higher level than
the pump (flooded suction), pipe the exhaust higher than the product source to prevent
siphoning spills.
Freezing or icing-up of the air exhaust can occur under certain temperature and
humidity conditions. Use of an air dryer unit should eliminate most icing problems.
BETWEEN USES
When used for materials that tend to settle out or transform to solid form, the pump
should be completely flushed after each use, to prevent damage. Product remaining
in the pump between uses could dry out or settle out. This could cause problems with
valves and diaphragms at re-start. In freezing temperatures, the pump must be drained
between uses in all cases.
FLAP VALVE SERVICING
Valve inspection requires removal of 3/8" hex nuts and elbows. When the top suction elbows
are removed, the valve and seat are connected as an assembly. When the bottom discharge
elbows are removed, the valve and seat stay with the outer chamber. Visual inspection and
cleaning is possible. If parts are to be replaced, remove the self-locking nuts and all parts
are accessible.
DIAPHRAGM SERVICING
Diaphragms can be inspected or the diaphragm assembly removed without
removing the suction and discharge flanges. Remove (8) nuts around the chamber
flange, and the housing assembly will pull off. Flap valves can be inspected for
proper seating at this point as well as the diaphragm. Use care to keep foreign
matter from behind the diaphragm. The opposite diaphragm may be inspected by the
same procedure. If either diaphragm has to be replaced, follow closely these steps:
Pull the outer diameter of one diaphragm off the (8) capscrews. NOTE: One
side only! On the free diaphragm assembly, use a 3/8" allen wrench to turn the
assembly (diaphragm, plates and screw) loose from the shaft. Once the assembly
has turned, it will turn out by hand by use of the diaphragm. Now the opposite
diaphragm assembly and the drive shaft will pull free from the capscrews and pump
intermediate assembly. The interior components consisting of sleeve bearings, rod
seals, and pilot valve actuator bushings are now accessible for service if required.
Hold the shaft in a clamping device making sure to protect surface of shaft so as not to
scratch or mar it in any way. The diaphragm assembly will turn loose. To disassemble
the components, turn a 1/4"-20 capscrew by hand into the tapped hole in the inner
plate. This keeps the plate from turning while the socket head capscrew is removed. To
do this, place assembly in a vise so the two protruding ends of screws are loose in the
vise jaws (about 3/4" apart). Turn the center screw loose from the back plate and the
assembly will come apart.
x75afvmdl7sm-rev0411 Page 7

REASSEMBLY
All procedures for reassembling the pump are the reverse of the previous instructions
with further instructions as shown:
1. The diaphragm assemblies are to be installed with the natural bulge outward
or toward the head of the center screw. Make sure both plates are installed with
outer radii against the diaphragm. After all components are in position in a vise and
hand tight, set a torque wrench for 480 inch pounds (40 ft. pounds) (54.23 Newton
meters) or, 600 inch pounds (50 ft. pounds) (67.79 Newton meters) for Santoprene,
using a (3/8") allen head socket. After each diaphragm sub assembly has been
completed, thread one assembly into the shaft (held near the middle in a vise having
soft jaws to protect the finish) making sure the stainless steel washer is in place on the
capscrew.
Make sure 1/4"-20 mounting screw has been removed and that the bumper (Item
#19 on drawing) is in place in the shaft.
Install this sub assembly into the pump and secure by placing the outer chamber
housing and capscrews on the end with the diaphragm. This will hold the assembly
in place while the opposite side is installed. Make sure the last diaphragm assembly
is torqued to 30 ft. lbs. (40.67 Newton meters) before placing the outer diaphragm
over the capscrews. If the holes in the diaphragm flange do not line up with the holes
in the chamber flange, turn the diaphragm assembly in the direction of tightening
to align the holes so that the capscrews can be inserted. This final torquing of the
last diaphragm assembly will lock the two diaphragm assemblies together. Place
remaining outer chamber on the open end and tighten down the securing nuts
gradually and evenly on both sides.
Caution should be used while reassembling Flap valves. The valves are designed
for some preload over the retainer hinge pad. This is done to insure proper face contact
with the seat. After all parts are in place, tighten the lock nuts down on the assembly
to the point where visual inspection shows that seat and valve face mate without gap.
This is important for dry prime. However, after priming action has started, valves will
function due to differential pressure without concern or trouble.
PILOT VALVE
The pilot valve assembly is accessed by removing the main air distribution valve
body from the pump and lifting the pilot valve body out of the intermediate housing.
Most problems with the pilot valve can be corrected by replacing the o-rings. Always
grease the spool prior to inserting it into the sleeve. If the sleeve is removed from the
body, reinsertion must be at the chamfered side. Grease the o-rings to slide the sleeve
into the valve body. Securely insert the retaining ring around the sleeve. When reinserting
the pilot valve, push both plungers (located inside the intermediate bracket) out of the
path of the pilot valve spool ends to avoid damage.
PILOT VALVE ACTUATOR
Bushings for the pilot valve actuators are threaded into the intermediate bracket
from the outside. The plunger may be removed for inspection or replacement. First
remove the air distribution valve body and the pilot valve body from the pump. The
plungers can be located by looking into the intermediate. It may be necessary to
use a fine piece of wire to pull them out. The bushing can be turned out through the
inner chamber by removing the outer chamber assembly. Replace the bushings if pins
have bent.
